FAQ: Where do I Mount the Jack for Lifting the Car?

The slightest incline will cause the scissor jack to slip. I helped an old guy out with flat last month (Volkswagen Passat). Couldn't move it. Had to deal with where it was. Stupid jack tipped and fell over. These little jacks aren't made for anything but flat ground.

The Volks jack had a groove as well. Only one spot to put it. It was the bottom that slid out and caused it to tip.

O.K., I can believe it tipped if not used on flat ground. Mine has looked iffy a few times while using a floor jack on the other side. I may have been lucky that it didn't slip, but it was on level concrete. I've avoided using it since seeing how it tips over.

This won't work well with the Riv because of the single-pipe-dual-outlet BUT you could blow it up with a car having single-outlet exhaust:
